Use of argon ions for the preparation of nuclear filters

A Device for Producing Nuclear Membranes by Bombarding Polymer Films with Argon Ions

“…Films were irradiated on an ê7-å (ì-120) cyclotron by eightfold-charged argon ions with an energy of 1.0-1.1 MeV/nucleon [1]. A 10-µ m-thick, 320-mm-wide polyethylene terephthalate film was subjected to ion bombardment.…”

“…It is possible to create on their basis filters for removing suspensions and microbes from drinking water, for plasmaphoresis, for the clarification and microbiological stabilization of medical preparations, for thoroughly cleansing gas and air of aerosols and microbes, for the microbiological analysis of water samples, and for the production of sublimated objects [1][2][3]. One of the basic requirements for this is a uniform distribution of pore density over the film's surface both edgewise and along its length, which can reach hundreds of meters.…”
